l justing nuts 18 bearing'on the topof said 1 measuring chamber. f The pipe 15 discharges into the cup iwhich has a small outlet ori- [ice 19 in the bottom thereof for a purpose hereinafter described and the float has a through passage 20 arranged in line with the discharge pipe 15. A counter 21 of anv suitable construction-is provided ard operated by an arm 22 carried on the rod 11 to count the numbemof discharges of liquid from the measuring chamber into the container 2.

The container communicates with the upper portion of the measuring chamber by means of a stand pipe 23 so that the air can pass freely from one to the other.

2-! is the outlet from the container.

The operation of the meter is as r'ollows a- As the liquid is drawn oflt from the container the level gradually falls until it reaches a level below that of the orifice 19 in the cup 4: whereupon the float pulls down valve 7 thus allowing the liquid to enter the measuring chamber through the inlet pipe The liquid will continue to flow into the measuring chamber until its level rises sufiiciently to start siphonio action in the siphon situated in the measuring chamber whereupon the contents of the measuring chamber will be discharged into the cup 4: and will overflow into the container. The first part of the discharge causes the float to rise and operates the counter 21 and also the needle valve 7 to shut off further supply of liquid to the measuring chamber. As the liquid passes out of the container that contained in the cup 4: escapes through the orifice 19 until the cup is emptied whereupon the series of operations above described is repeated.

The quantity of liquid which will be dis charged from the measuring chamber can be regulated by adjusting the height of the bell 13 of the siphon by means of the adjusting nuts 18, and the meter may thus be calibrated.

I claim:

1. In a liquid meter the combination of a measuring chamber having an inlet, a valve for controlling said inlet, a container having a free outlet, a siphon for periodically discharging the liquid from the measurin chamber into the container, a. float situated in the, container for controlling the inlet 1 valve of the measuring chamber and a cup the rod 11. and raises the stem 8 of the needle which surrounds the float and into which valve of the measuring chamber, a counter also operated by said float and a cup which surrounds the float and into which the liquid is discharged by the siphon, the said cup having an outlet orifice, for the purpose set forth. v

3. In a'liquid meter, thecombination of Copie: of this patent may be obtained for a measuring chamber having an inlet, a valve for controlling said inlet, a container having a free outlet, :1 siphon for periodically discharging the liquid from the measuring chamber into the container, a floatsituated in the container for controlling the inlet valve of the measuring chamber, a

counter, also operated by said float, a cup which closely surrounds the float and into which the liquid is discharged by the siphon,

the said cup having an outlet orifice, and

means for regulating the quantity of liquid discharged from said measuring chamber,

for the purpose set forth.
